Tufte Principles of graphic excellence

principis d'excelència gràfica de Tufte(1983) fins a d'altres propis de la recerca social, cal contemplar que la visualització ha de ser una representació ben dissenyada de dades interessants (substància, estadística i disseny); ha de comunicar idees complexes de forma clara, precisa i eficient; ha de donar a la persona observadora el nombre màxim d'idees en el mínim de temps i el mínim de recursos; ha de ser, a ser possible, multivariada; i , finalment, ha de dir la veritat de les dades, i així, ser fiable (Tufte; 1983). Aportacions de l'àmbit del disseny de la informació i des de una perspectiva centrada en el ser humà han servit per incorporar altres qüestions com el fet que les visualitzacions han de ser manejables; han de donar una vista de la informació global i abarcar la totalitat d'informació que s'ha de visualitzar; han de ser interactives i els espais d'informació han de ser navegables; i finalment; també s'ha considerat que la visualització ha de ser receptiva, panoràmica (Horn: 1999).i sensible a les variacions

Mapping physical territories

mapping is a process of creating, rather than revealing, knowledge. troughout the process of creation, a large number of subjective -often inconcious - decisions aremade about what to include and what to xlcude, how the map will l , and what the map is seeking to communicate. In other words, a map is imbued with values and judgements of the people who construct it. Moreover, thet are undeniably a reflection of the culture and broader historical and political contexts in which their creators live. As such, maps are not objective, neutral artefacts but are constructued in order to provide particular impressions to their readers.   Maps then, are situated, embodied and selective representations. ,
